<p>How important are the i-clickers? Are you actually going to use them, because I read somewhere that it was useless.</p>
<p>I'm asking this because I remember seeing them at the Illini Union Bookstore last week, but I don't remember what class it was for.</p>
<p>Also, a separate question is what is the difference between iclicker1 and iclicker2?</p>
<p>You are required to have an I-Clicker for some classes to get participation credit (physics). Other classes have no need for it I’ve heard. Wait for the first week or so to go by to see if you need it. Most professors don’t care about not having all the supplies for the first two weeks anyways.
The difference between one version and the other is the second version has a screen that shows the battery life and what letter you choose, along with costing more.</p>
<p>thanks for the detailed reply!</p>
